Hi Benedikt, > txt := "123"; > txt := ATTR__text; % does not work. How do i get the value from
You are so nearly right. Two underscores for Therion's built in properties. One underscore for -attr properties. ATTR_text I have an example here: https://therion.speleo.sk/wiki/metapost#rope_lengths Regarding your main question, no I don't know how to create custom label ornamentation (it looks like black magic to me). But you can see what I have learned here: https://therion.speleo.sk/wiki/metapost#adding_custom_styled_labels_at_any_point_linepoint And then you need to look through the Metapost debugging output for: vardef p_label@#(expr txt,pos,rot,mode) = That is the code that actually draws labels with ornamentation. It then calls functions like this: process_circledlabel That in turn - after writing a label - uses some kind of bounding box measuring to decide how to ornament it. Check out the function: def write_circ_bbox expr q = Good luck sir. If you work it out, please document it so we can all learn how it all works. :) Cheers, Tarquin _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
